Boom Re circulation System - Pressurized oil is efficiently recirculated in the boom circuit, assisted by the boom self-weight when the boom lowers.This design delivers more pressurized oil to the arm from the pump to increase arm lowering speed in combined operation of the boom and arm.

Boom- and Swing-Priority Modes - The boom- or swing-priority mode can be selected for higher production.

Swing-Priority Mode - When swing angle is large in a cycle of digging, swinging and dumping, swing speed increases to reduce a cycle time.
